High percentages of bilateral asymmetry are consistent with uni- and bimanual hunting techniques and food processing, possibly beginning in adolescence.

Comparisons with global hunter-gatherers reveal similar asymmetry patterns, though local deviations may reflect adaptations to specific environmental and economic contexts.
